最近看到一篇病例报道的文献,描述一个5岁免疫缺陷病的病人,其中有一句好像是关于病人食物方面
Ingestion of eggs and milk had been restricted until 43 months of age, when he passed the open challenge test.
请问这个open challenge test.是个临床上的什么实验啊?因为他43个月前没有通过这个实验,所以限制了鸡蛋和牛奶吧

直翻译：开放的挑战测试

没有上下文看不出啊

公开的应对试验??/

A 5-year-old Korean boy was admitted because of fever, cough,and otorrhea for a week. His parents were not consanguineous.He had no remarkable perinatal problems and had been vaccinated as scheduled. He had a history of atopic dermatitis since 6 months of age. Ingestion of eggs and milk had been restricted until 43 months of age, when he passed the open challenge test.Of note, past medical history also revealed recurrent infections,including multiple episodes of oral candidiasis. He was treated with antibiotics for an abscess on the scalp caused by group A b-hemolytic Streptococcus species at 4 months of age. He had a history of 3 hospitalizations for pneumonia without pneumatocele.Suppurative cervical lymphadenitis caused by Staphylococcus aureus, which occurred at 18 months of age, was successfully treated with incision, drainage, and antibiotics, but it recurred several times afterward.
这是上下文,谢谢

蛋和牛奶的摄取被限制直到43个月大（年龄达到43个月）他通过了公开的激惹试验的时候
